CCTV - THE NOW AND THEN
Whilst Britain is clearly the leading nation in implementing CCTV, other countries are quickly following the lead. North America, Australia and some European countries, which a few years ago .........

In the past decade, the use of Closed Circuit Television (CCTV) for surveillance and crime control has grown to unprecedented levels. In Britain, annually, between £150m and £300m per annum is spent on a surveillance industry involving an estimated 300,000 cameras covering shopping areas, housing estates, car parks and public facilities.
CCTV is very quickly becoming an integral part of crime control policy, social control theory and community consciousness. Police and politicians promote it as the primary solution for urban dysfunction. It is no exaggeration to conclude that in Britain the technology has had more of an impact on the evolution of law enforcement policy than just about any technology initiative in the past two decades.
In addition to this, the CCTV industry has been revolutionised by the comparatively recent adoption of Digital Technology. Signals produced by digitally based CCTV systems can easily be routed to any user needing to view them via their organisation’s LAN, WAN or Modem. This is in contrast to the situation in the past with analogue systems, which could only be viewed at a central point, and could not be accessed by users in other locations.
Analogue CCTV systems traditionally store video at the rate of one frame every three seconds, often resulting in crucial events not being captured. Conversely, digital systems are able to capture and store video footage up to 25 frames per second, ensuring that nothing is missed.
The storage of video captured by analogue systems can be an administrative nightmare, with one video recorder per camera and frequently 31 video tapes per recorder being used in rotation. Searching through the tapes could be extremely laborious. In contrast, with the hard drive based storage of digital video footage, one video management-recording unit can store the output from 16 cameras for several days on a 120 gig hard drive, and it can replay any event instantly.
Digital Monitoring and Recording Systems Software allows the user to point movable dome cameras as well as offering precise control over what footage is stored, and for how long. Recording can take place continuously, either on schedule, as the result of an alarm, or even when the system detects motion.
VISION GUARD CCTV UK have also installed a number of CCTV systems that monitor critical points in production processes and allow executives to view the footage on their desktop computers, or even by dialling into the system from remote locations.
VISION GUARD CCTV UK systems are tailored according to individual needs and can range in size from a 4-camera unit to a multi server configuration with dozens of cameras and many terabytes of storage space.
DEFINITION
CCTV (closed circuit television) is a television system in which signals are not publicly distributed; cameras are connected to television monitors in a limited area such as a store, an office building, or on a college campus. CCTV is commonly used in surveillance systems.
VISION GUARD CCTV UK simplifies a video management system by digitally recording images directly on a computer hard drive. The state-of-the-art technology easily integrates with existing security infrastructure and technology. It works with existing cameras. It also has a function to utilize existing VCR’s as a backup unit to record certain incidents in conjunction with the VISION GUARD CCTV UK system.
